T0 all whom it may concern:

Be it known that I, CALVIN B. Paroma citizen of the United States, residing at Glenellyn, in the county of Dupage and State of Illinois, have invented a certain new and useful Improvement in Draft-Rigging for Railway-Cars, of which the following is a full, clear,'concise, and exact description, reference being had to the accompanying drawings, forming a. part of this s'pecication.

My invention relatesl to improvements in draft rigging for railway cars.

- The object of my invention is, to provide a-draft rigging of simple construction and efiicient operation.

ln the drawings forming a part of this specification, Figure l is a side elevation partly in vertical longitudinal section of a draft rigging embodying my invention, and showing the parts in normal position. Fig. 2 is a plan view partly in horizontal section on line 2 2 of Fig. 1, and showing the position of the parts when in full buff. Fig. 3 is a cross seotiontalren on line 3--3 of Fig. 1. Fig. 4 isa plan view of the 4yoke -member showing a modification thereof.

Referring to the drawings, the numerals 5-5 indicate draft members, the car-frame to which the draft rigging is applied; 6-6 stop members secured to the inner faces of the draft members,.prefer ably by the rivets 7-?, the said stop members being each provideduwith front stop 'shoulders 8, front limiting stop shoulders 9, rear limiting stop shoulders l0, and rear stop shoulders 11. Thedraw-bar 12 (only the rear end thereof-,being shown in the drawings) is transversely slotted for the passage of the coupler key' 13, the ends of said .key passing through slots 141-14 in adjacent portions of the vstop members and l draft members, the said slots being longitudinally extended to permit the forward and rearwardftravel of the key 13 therein. Front and rear followers 15v and 16, re spectively. are mounted between the draft members'.Av Upper and lower sets of compression resisting members 17 and .18, respectively, aremounted between the followers. Each set of compression resisting members comprises preferably an outer spring 19 and an :inner spring 20 nested therein. A tail bolt 21 'serves its usual function of connectiiigthe draw-bar to the compression f or parts of drawn forwardly,

provided with transverse slots 28- 28 forthe passage of the coupler key 13. Thearms 23 and 24 of the tail bolt are preferably integrally formed, respectively, with the upper and lower plates 26 of the member 21 of the t'ail bolt, and pass rearwardly therefrom" through upper and lower longitudinal x openings 29-29, respectively, formed inieach of the followers. Thus the followers are in sliding engagement upon the rearwardly extended arms of the tail bolt, and operate therein in a manner hereinafter described. Near their rear ends the arms 23 and 24 of the tail bolt are each provided'with a vertical slot 30 to receive each a pin 31, the pins 31 preferably consisting each of the key-like portion 32 and a head 33, preferably integral therewith. The said pins are adapted to engage against the rear face of the rear'follower 16. A saddle 50, secured at its ends to the draft'members 5, preferably by the bolts 51-51, is adapted to support the springs between the draft members, and the springs in turn support the tail `bolt and the followers mounted thereon.

. @n forward movement of the draw-bar, the tail bolt 21, through the coupler key 13, the arms 23 and 24 thereof drawing the rear follower forwardly, compressing the springs between the followers, the front follower being stopped against forward v `movement by its engagement against the front stop members 8. The forward movement of the rear follower is llimited when the follower engages the rear limiting stop shoulders 10.

n rearward movement ofthe draw-bar, the front follower is engaged by the rear end of the draw-bar and` by the rearward face 35 of the front hollow head of the tail bolt, the front follower is forced rearwardly, compressing the springs between the followers,'the rearward movement of the rear follower being stopped through its engagelower is limited when it engages against the front limiting stops 9. On rearward movement of the draw-bar the arms of the tail bolt slide rearwardly in the longitudinal openings in the rear follower, and in forward movement of the tail bolt the arms thereof slide forwardly i'n the longitudinal perforations in the front follower. Inthe modification of the tail bolt illustrated iii Fig. 4 of the drawingsthe tail boit head 40 and the rearwardly'extefhded arms 4l thereof are divided longitudinally along their central vertical line, the tail bolt being in two pieces 42 and 43, respectively, the arms near their rear ends being provided on their inner faces with oppositely arranged registering vertical grooves 44-44 which when the two parts of the tail boltare in vassembled position form a vertical slot 45 forthe passage ofl a locking key 46. A cup 47 for each arm is adapted to inclose the rear ends of the two pieces of each arm when in assembled position, and serves with the key 46 to lock the two members of the tail bolt together. The two pieces of the tail bolt are also held together by the followers,

erforations in which the said arms are adapted to pass through.

I claim A 1. In a draft rigging for railway cars, in combination, draft members, stop mem- Gopies of this patent may be obtained for lowers whereby the followers thev iive cents each, by addressing th Washngton,D.G.I

bers secured thereto, a draw-bar, a tail bolt secured to the draw-bar, followers, and compression resisting members between the followers, the tail bolt comprising two lateral sections, said sections when assembled forming a hood to receive the draw-bar, and rearwardly extending arms, the said arms being provided at their ends with an inclosing cup,

and a 2. ln a draft rigging tail bolt having a hood at the forward end to receive the butt end cf a draw-bar and provided with an arm extending rearwardly from the hood, said tail bolt comprising two members each of which has halves of the hood and arm formed integrally, and means for securing the two parts together.

3. in a draft rigging for railway cars, the combination with draft members having stops, a draw-bar, followers, shock absorb# ingmeans between the followers, of a tail bolt secured tothe draw-bar, said tail-bolt comprising two lateral sections forming, when assembled, rearwardly extending arms, saidarms passing through slots in the folassist in reeach section PATCH.

taining the sections together, forming a portion of each arm. CALVN B.
